Abstract

Winter tyre (1) for vehicle wheels (11), comprising a tread band (14) mouled with a relief pattern which comprises at least one row (15) of blocks separated by transverse grooves (22, 23) intersecting two circumferential grooves (16, 17). Each block is formed by two portions (18, 19) which are axially adjacent with respect to a longitudinal axis which is preferably aligned with the equatorial plane (Y-Y). Each portion (18, 19) of the block has an irregular rhomboidal shape which approximates the shape of a plant leaf. The transverse grooves (22, 23) have a cross section widening (30) with a substantially curvilinear profile in each of the two axially adjacent blocks. Said cross section widenings (30) are useful for trapping snow. The frontal profiles of the axially adjacent portions (18, 19) of the circumferentially adjacent block comprise at least two successive curvilinear portions (28, 29) which are different from each other and are designed to form means of attenuating the noise arising from the contact of the tread pattern with dry roads when the tyre is in the rolling condition.
